GENERAL BOTANICAL CHARACTERISTICS:
Habit: Longstalk cranesbill is an annual that reaches on average 5.9–12
inches in height, with a maximum of 24 inches. The stem is more or less
erect, sparsely hairy and quite branched, the long, slender stalks being a distinguishing feature.
Leaves: The leaves are opposite, approximately pentagonal and palmate
and the leaf lobes have two to three deep cuts. The leaves are often edged
red andstand clear of the stems. The leaf shape is similar to a pigeon's foot
(hence the Latin epithet columbinus).
Flowers: The flowers are pink to purple, 0.59–0.79 inches in size, with
five obovate-heart-shaped petals as long as the sepals. The petals are 7-9
mm long, only slightly cleft, with distinctive veining. The corollas are sur-
rounded by bristle-tipped sepals which are also slightly striped and are as
long as the petals.
Fruit/Seeds: Five, erect, mostly hairless, non-glandular, about 2.5 cm long, single-seeded, rounded base, beaked, nutlike segments surrounding remnant elongated style column of each flower. Each nutlike segment has a 4 - 5 mm long, narrowed beak at its tip, which is attached to the lower part of the style column, and then is pulled upwards by the coiling outer wall of the style column, yet stays attached to the entire fruiting structure and ejects the seed from the main body of the nutlike segment.
